Expected 2 keywords got 6

How can this problem be solved for example, The Execute special command on accepts 2 arguments, but I want to make it accept more. I want these two commands to be together so that I can replace the yaml file of a docker image at once

Execute special command on     ${cluster}        kubectl exec -n ${namespace} get statefulsets/postgresql-pod -o yaml | sed "s#image: docker repo /stolon#image: bbbdocker repo/stolon#"
Execute special command on     ${cluster}        kubectl -n ${namespace} replace -f -

Use @{varargs} in your argument
